Verdict
The clearest difference is in-app purchases: BlackLight Summit at none against Glow Lamp's 1. BlackLight Summit also leads on ads (none vs shown). Glow Lamp's advantage is update cadence (every 4 months vs every 12 months). On price, device support and iOS requirement there is nothing between them.
